CIR-THEEL ELECTRIC LIGHTING.
Iron, Inc Sprfnraeld Republican

Tho experiment Ioi lighting with electricity gcner-
ated by heels is being tried by the Connecticut
Valley road on train OF two passenger cars ana
occupies a closet built on one side OF the baggage
section of the next the entrance to the smoking
apartment. There are sixteen incandescent lamps to

irrepulat power 10 store electricity enough TO use
when the dynamo net In motion, and to run the
DYNAMO With the car going In either direction. His
machinery Tor running the d ,namo is comparatively
simple in construction Attached to the journal at
one end of tho car is 12inch section pulley, over
which an iron cable revOyes, running counter shalt
on n slight elevation above, 30 feet away, by
l6inch pulley. The cable is 80 eet long, y inch IN
thickness and made up OF 1872 wire strands. Iron
rollers suspended rom the car draw up the lower and
uress down tho upper hs Ives OF tho cable, guiding
It and keeping it taut The cable runs directly In the
OF the car, while the belt to the aynamo aooye
is attached to n 36-inch pulley near the outside.
This pulley surrounds q l2inch friction wheel, two
shoes grasping IL firmly by means OF two double
springs Here an ingenious device regulates the speed

ready service when the station Is reached and the
wheels stop running MI. Barrett plans TO have this
battery stored when the lights not in in the
day time and there Is fear OF overcharging It, for
the surplus electricity will be dissipated in The air,
without doing injury.
Trouble has been met In keeping this stored
electricity from running back to the dynamo and
melting the brushes when the train stopped. The
dynamo has a 45-vot tension when in action, and az
SOON as this tension falls below that OF the storage
batteries the surplus current would crowd back and
destroy the machine, that Mr.. Barrett had tC
watch the switches closely and regulate them quickly
as the train approached every station. He obviate,
this trouble now, however, by small ball governor
which he put In last week This produces just the
